Abstract: PURPOSE:To prevent damage by twisting a hollow fiber film fibrous bundle, and dispersing a stress applied at the time when it is bent to a U-shape, in the cartridge for a water purifier, in which the hollow fiber film fibrous bundle is contained in a state bent in a U-shape in the inside case. CONSTITUTION:In the cartridge for a water purifier, an inside case 2, the upper cover 3, and plural filters 4, 5 and plural O-rings 6, 7 are attached to a main body case 1. Also, in the inside case 2, a hollow fiber film fibrous bundle 8 is contained in a state bent in a U-shape, and both its end parts are supported by a potting material 10. Moreover, between the main body case 1 and the inside case 2, activated charcoal 9 is provided. In such a constitution, the hollow fiber film fibrous bundle 8 is formed so as to be twisted.

IPC: H02J3/12
Filed: 1987-12-21
Abstract: PURPOSE:To compensate a voltage variation together with a waveform distortion and a flicker by interposing, in series with an adding polarity, a compensation power source for always generating a compensating voltage in response to the variation in the voltage of a power source of a system side between the system side power source and a load. CONSTITUTION:A compensation power source 10 for always generating a compensating voltage VH in response to the variation in the voltage VS of a system side power source 1 is interposed in series with an adding polarity between the power source 1 and a load 7. The power source 10 rectifies by a rectifier 2 the power source voltage CVS to charge a capacitor 3 having a large capacity and opens/closes an inverter 4 by a signal responsive to the variation in the voltage VS output from a controller 8, thereby generating a voltage V1. The voltage V1 is applied to the primary side of a coupling transformer 5, the voltage VH is generated from its secondary side, added to the voltage VS as a voltage VL, and applied to the load 7. Thus, the variation in the voltage having large varying width, and the variation in the voltage having a small varying width, such as a waveform distortion, a flicker or the like can be compensated.

Title: Water-permeable bag structure for sand pile formation, and manufacture, application and construction thereof
Inventor: ARAI TOMOSUKE
IPC: E02D3/10
Filed: 1990-11-29
Abstract: PURPOSE:To greatly raise the draining function of water by a method in which one or more water-permeable and long drain tubes are set along the longitudinal direction of a sand pile-forming vertically long and thin water-permeable bag structure, and sand or the like is packed into the bag structure to form a sand pile through which water is drained, even through the drain tubes. CONSTITUTION:A water-permeable thin and long drain tube 2 is directly set on the inside or outside of a water-permeable bag structure 1 of synthetic resin net or woven fabric to integrally connect the structure 1 with the pipe 2 from the lower end to the upper end. The structure 1 together with the tube 2 is penetrated into soft ground to pack sand into the structure 1. Water collected from the surrounding water-containing layer is passed through the sand pile and discharged even from the tube 2, where the water can only pass through the tube 2, but sand and other foreign matter do not pass. Great amount of water can thus be collected from the surrounding to attain sufficient accelerating effect of consolidating subsidence.

Title: Optical recording medium
Inventor: UEDA YUTAKA
IPC: G11B7/2472
Filed: 1990-11-28
Abstract: PURPOSE:To reduce regenerative deterioration by forming a light absorbing layer from a mixture of a dye substantially pervious to laser beam and a dye absorbing laser beam. CONSTITUTION:A light absorbing layer 2, a reflecting layer 3 and a protective layer 4 are successively laminated to a substrate 1. The function of the light absorbing layer is divided into function absorbing laser beam to convert the same to heat and function forming a recording pit by the melting, evaporation, sublimation or deformation of the layer 2 due to said heat. These two functions are separated to be separately provided to two kinds of dyes. That is, a dye absorbing laser beam takes charge of the first function and a dye substantially pervious to laser beam takes charge of the second function and the functions of the light absorbing layer are developed using the mixture of both dyes because it is unnecessary to absorb laser beam for the sake of the second function. The dye A absorbing laser beam generates regenerative deterioration but the dye B impervious to laser beam generates no regenerative deterioration.

Abstract: PURPOSE:To enhance input power factor and to suppress higher harmonics in input current by providing a current path for conducting input current from an AC power supply through a rectifier, an impedance element, an oscillation element in an inverter and a switching element. CONSTITUTION:Upon turn ON of a transistor Q2, an input current flows through a path of a rectifier DB, an inductor L3, a capacitor C4, an inductor L2 and the transistor Q2. The inductors L2, L3 and the capacitor C4 constitute an oscillation system and the current flow is subsequently inverted. Through which of first and second paths the current flows is determined by the resonance frequency of the inductors L2, L3 and the capacitor and the switching frequency. The process is repeated over the entire interval of the commercial period of the AC power supply Vs thus feeding input current continuously. When a filter circuit is additionally provided on the input side in order to remove high frequency components, a substantially sinusoidal input current having suppressed higher harmonic components can be obtained.

Title: Laying of vacuum sewerage
Inventor: YAMANAKA JUNICHI
IPC: E03F3/02
Filed: 1991-12-11
Abstract: PURPOSE:To smoothly carry sewage at the laying of vacuum sewearage in which lowering of the degree of vacuum due to a lift when the sewerage passes under an obstacle such as a river is prevented. CONSTITUTION:An upstream side vacuum sewer pipe 2 provided on one side of a river 1 and a downstream side vacuum sewer pipe 3 provided on the other side are connected to each other by a water pipe passing under the river 1 and by an air pipe 5 passing over the river 1. The upstream side vacuum sewer pipe 2 is provided with a vapor-liquid separator 11. Therefore, sewage in the upstream side vacuum sewer pipe 2 is allowed to flow into the downstream side vacuum sewer pipe 3 because of the principle of a siphon and so the degree of vacuum transferred from a vacuum station to the downstream side sewer pipe 3 is seldom lowered and is then transferred to the upstream side vacuum sewer pipe 2. Gas-liquid separation is efficiently performed by the gas-liquid separator 11 and only air is circulated through the air pipe 5 and only sewage through the water pipe 4. Thereby a good siphon effect can surely be obtained and smooth conveying of the sewage is made possible. The area for collecting sewage using a vacuum sewage collecting system can be enlarged.
